An efficient method for the synthesis of epoxides from carbonylcompounds, sulfoxides, and benzyne is presented. The strategy involved an epoxidation by a sulfur ylide which is formed in situ from sulfoxide and benzyne through the S–O bond insertion and deprotonation. This one-pot reaction proceeds under mild and base-free conditions, providing a convenient way to introduce the substituted methylene

A copper-catalyzed sulfinyl cross-coupling reaction of sulfinamides with aldehyde-derived N-tosylhydrazones is described. This approach enables facile access for the construction of structurally diverse sulfoxides via novel and efficient S–N/S–Cbond interconversions, features broad substrate scope, and accommodates various functional groups as well as pharmacophores. Moreover, the given sulfinyl cross-coupling
